Pennzoil announced the return of an iconic look for its brand in the Verizon IndyCar Series at Indianapolis Motor Speedway on Thursday. The "Yellow Submarine" design scheme which will adorn Helio Castroneves's No. 3 Dallara-Chevrolet launches a month-long schedule of activities celebrating the launch of Pennzoil Platinum and Pennzoil Ultra Platinum Full Synthetic motor oils with PurePlus Technology.

"Pennzoil is paving the way for our industry by offering modern and innovative synthetic motor oils made from natural gas," explains Rusty Barron, Vice President of Marketing, Pennzoil. "What we like about PurePlus Technology is that it starts with a base of pure, crystal clear base oil made from natural gas with fewer of the impurities found in crude oil, which is the traditional base for many other conventional and synthetic motor oils. We are pleased to honor the history of Pennzoil in IndyCar and at the Indianapolis 500 with the "Yellow Submarine."

Pennzoil presence in the Indy car racing began in the 1930s with Russell Snowberger, and based on his success, more IndyCar drivers began to use Pennzoil racing oil in their race cars. In 1979, Pennzoil joined Jim Hall's Chaparral team and the team painted the Pennzoil-sponsored car bright yellow. The look was so bright and distinctive, fans and competitors nicknamed it the "Yellow Submarine." The next year, Johnny Rutherford took the "Yellow Submarine" to victory lane at Indy for the first time.

After joining Team Penske in 1983, Pennzoil won two Indianapolis 500 races (1984 and 1988) in a similar yellow, black and red scheme with legendary driver Rick Mears behind the wheel. Mears, who still consults with Team Penske in multiple roles, is one of only three drivers to own four Indy500 crowns. Now, the iconic scheme will return for the 98th running of the Indianapolis 500 with Team Penske on the No. 3 Chevrolet driven by three-time Indy 500 champion Castroneves.

"My favorite memory of the Yellow Submarine is winning the Indy 500," said Castroneves when asked about the cars of the past. "I remember Rick Mears going down the straightaway and into Turn 1. You could spot the car – anywhere.....but I am going to drive the car! What a tradition and what a great honor."

Mears and Castroneves have combined for seven of Roger Penske's record 15 Indianapolis 500 victories. When Mears retired in 1992, he continued to work with Team Penske as a driver coach and consultant, a role he still fills today. Castroneves will be looking to tie Mears for the most wins at the Brickyard with a victory in 2014, and in his iconic yellow and red paint scheme.

"We are honored that Pennzoil is bringing a part of their heritage and the heritage of Team Penske back to life to help tell the story of their amazing advancements in motor oil technology," said team boss Roger Penske. "I have been around cars my entire life. This is the most exciting and innovative advancement in motor oil in decades. It's going to be a real game changer."

PurePlus Base Oil is found in many custom Pennzoil racing oils. Pennzoil Ultra Platinum Full Synthetic motor oil with PurePlus Technology 0W-40 motor oil is the exact same oil that Team Penske uses right-out-of-the-bottle in the Verizon IndyCar Series.

"Pennzoil is redefining the way consumers look at the motor oil category," said Barron. "Pennzoil Platinum motor oils with PurePlus Technology feature the capabilities to evolve with current vehicle technology to offer complete protection for today's engines."
